WHISTLE-VALVE ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

I Specification of Letters latent.

Patented Feb. 6, 1912.

Application filed November 20, 1908. Serial No. 463,525.

To all whom it may concern:

Be it known that I, ROBERT C. AnAMs, a citizen 01? the United States of America, re siding at l/Vilton, county of Fairfield, State of Connecticut, have invented an Improvement in Whistle-Valve Attachments for Internal-Combustion Engines, of which the following is a specification.

This invention relates to an attachment to be applied to internal combustion engines.

It is of the general character disclosed in U. S. Patent No. 591,521 granted October 12, 1897 to George F. Arp.

The accompanying drawing is a sectional view. i

1 indicates theengine cylinder in a threaded aperture in the wall of which is fitted a I threaded cast metal plug 2 having an opening 3 extending longitudinally through it. lln a threaded aperture ,in the side of the plug is fitted a pipe 4 that communicates with the bore of the plug and has applied toits outer end a blow-off valve 5 of any suitable construction. The outer end of the plug is threaded, as at 6, to receive the internal thread 7 formed in a cavity in the end of a body piece 8 that is a metal block preferably clrcular in cross section and tooled to produce, annular ribs?) to increase its heat radiating capacity. Within the cavity in the body 8 adjacent the plug 2 is screwed a thimble 10 having four parallel wire gauze partitions 11 beyond which the cavity is contracted to a bore or opening 12 of considerably less diameter than the cavity and extending through the body 8 and communicating with a second cavity 13 at the other or outer end of the body. The latter cavity 13 has a conical valve seat 14 surrounding the opening or bore 12 and coiiperating with such valve seat is a conical check valve 15 loosely mounted on a spindle 16 arranged axially in line with the passage 12 and carried by a screw plug 17 screwing, into a threaded aperture in the outer end of the body 8. The cavity 13 has a lateral extension 18 the inner wall of which is threaded of course it may to receive the hollow threaded plug 19 the outerend of which is threaded to receive apipe 20 leading to a storage tank 21 placed at any suitable or required distance from the cylinder of the engine and that may be provided with a pressure gage 22, and is provided with a whistle 23, the latter to be operated from any point by a cord, chain, lever or other suitable connection.

The wire gauze partitions act as sepa-,

raters to prevent ignition of the stored gases beyond the check valve which gases will in 4 practice probably have mixed with them more or less of the explosive mixture admitted to the engine cylinder. The gravity check valve should be adjusted for a very small lift. A gravity valve is preferred, but be backed by a spring of suitable strength. The body 8 of the device has large capacity for radiation of heat absorbed by it from the hot gases. The device is solid and rigid. It can be screwed into the aperture of the engine cylinder and then connected by a pipe, such as 20, either rigid or flexible, with the storage tank to be appropriately located as desired. The construction is heavy and substantial and the device may be applied with facility to any type of internal combustion engine.

I claim:

1. A whistle attachment for an internal combustion engine, comprising a hollow metal plug adapted to be connected to the combustion chamber, a blow-01f valve connected with said plug, a body part of metal having radially arranged projections to afford increased heat radiation capacity to.

cool the gases as they pass through said body portion, and havlng two enlarged chambers ateach end and a passage connecting said .chambers, a thimble fitted in the cavity adjacent said plug provided with a plurality of wire gauze partitions, a conical valve located in the outer cavity of said body-,-and cooperating with a conical valve seat/a hollowplug communicating with the latter cavity, and a' pipe leading therefrom.

2. A whistle attachment for an internal radiation, and a check valve appropriately 10 combustion engine comprising a hollow located in the attachment. 7 metal plug adapted to be connected to the In testimony whereof, I have hereunto combgstiori1 chagibelr, a:blow-ofi valg e consubscribed my name. necte wit sai p ug, connections etween said plug and the storage tank, Wire gauze ROBERT ADAMS partitions interposed in said connections for Witnesses:
